Hey guys

So recently i built my first PC:

Intel i5 2500k
Radeon HD 6970
Gigabyte GA-Z68x-ud3-b3
rosewell 1000w psu
4gx2 gskill f3-12800cl9d-8gbrl 1600 ram
hitachi 7200 rpg 32m sata2 hard disk

And ive been playing oblivion a bit. Usually i get about 60 frames maxed with a few texture packs however every now and then i get a sudden drop from 60 frames to about 5 frames a second for about two seconds or so. This as you can imagine can get really annoying. Do any of you know what is causing this and what i can do to fix it?

Thanks guys.
